As we saw in the previous post, the basic function of the "Blinker" object is to control the states of on and off of one or more channels autonomously. With it, we can control a few LEDs, a single LED, relays, or any other device that we want, reversing its value based on the seconds that we have defined.

The Blinker object is a simple object that can send zeros or ones with a certain cadence from one to eight different channels. In this example we will look at its simplest use: controlling eight LEDs through a GPIO interface.
